Objective To compare the influence of open access journals ( OAJ ) of biomedicine on academic exchanges by empirically analyzing the journals enrolled in the Chinese science citation database-the core (CSCD-C).Methods Multivariate statistical analysis was performed on OAJ and non OAJ in CSCD by using bibliometric and statistical methods,SPSS software and rank-sum test.Results The OAJ were accounted for only 31.63% of the total enrolled journals,the average ratio of funded papers in OAJ was 72.29%.Statistical journals had high influence in the discipline.The selfcitation rates of clinical medicine OAJ and special medical OAJ were high.The average impact factor and h index in biological OAJ were high.The average impact factor of preventive medicine OAJ was high.The average h index of comprehensive non OAJ was high.Conclusions The distribution of OAJ is uneven among different disciplines.The ratio of funded papers is higher in OAJ than in non OAJ with insignificant differences in discipline influence.

Objective To explore the effect of continuous nursing based on WeChat public platform on the patients with high risk of pressure ulcers. Methods Selecting 165 pairs of high-risk patients and their caregivers from the emergency department of pressure ulcers in the General Hospital of Chinese People′s Armed Police Forces, and they were divided into control group and experimental group by paired random method. There were 83 pairs in control group, and 82 pairs in experimental group. The control group gave oral education according to the traditional model, and adopted the way of telephone follow-up for continuous nursing. While the experimental group let patients and their family members follow the Wechat public account that specially developed on Wechat platform and get continuous nursing in new models to come true networking health education and communicate with patients and their family members by multi-dimensional nurse. After 3 months intervening, compared patients′quality of life, the care behavior of caregivers and acquisition of knowledge of pressure scores, the incidence of pressure ulcers, degree of satisfaction of high-risk patients and caregivers between the two groups. Results The psychological function score, social function score and quality of life score was respectively ( 67.61 ± 1.67), (58.60 ± 1.52), (50.41 ± 2.70) points in experimental group, and (63.21 ± 1.30), (53.23 ± 1.92), (45.83 ± 2.59) points in control group, the comparative difference of the two groups was statistically significant( t=-4.638,-4.930,-2.749, P<0.05). There was no significant difference in the material life and body function score between two groups(P>0.05). The care behavior of caregivers score and pressure sores knowledge score was respectively (50.84 ± 1.92), (27.83 ± 1.48) points in experimental group, and (46.43 ± 2.40), (19.28 ± 1.31) points in control group, the comparative difference of the two groups was statistically significant (t=-3.192,-9.738, P<0.05 or 0.01). The incidence of pressure ulcers was 15.9%(13/82) in experimental group, significantly lower than that in control group (50.6%, 42/83), two groups was statistically significant (χ2=22.413, P<0.01). The satisfying degree and scores of patients or caregivers for follow-up form, nursing service attitude, follow-up content and the total score was respectively (24.83 ± 3.11), (24.10 ± 2.55), (25.03 ± 2.12), (76.23 ± 2.17) points in experimental group, and (18.34 ± 1.41), (17.41 ± 1.34), (19.85 ± 1.92), (63.25 ± 3.03) points in control group, the comparative difference between two groups had statistical significance (t=-7.797--4.061, all P<0.01). Conclusions Utilizing Wechat public platform continuity of care for patients at high risk of pressure ulcers can improve the patients quality of life, reduce the incidence of pressure ulcers, improve the efficient communication of nurses and patients, and enhance the degree of satisfaction of the patients. This method is convenient, shortcut, economic, practical and worthy for clinical use and promotion .

Objective To study the effect of hydrogen on mitochondrial function in cerebral cortex after cerebral ischemia/reperfusion(I/R)injury in rats. Methods 48 male SD rats were randomly divided into sham operation group(sham group),brain I/R injury group(MOD group),hydrogen treatment group(H2group). 24 hours after reperfusion,the neurological deficit scoring was performed. The changes of mitochondrial membrane potential(△ψm),permeability openness(MPTP),ROS production rate and mitochondrial swelling were detected. Results Compared with the Sham group,neurological deficit score,MPTP openness,mitochondrial swelling degree and ROS production rate were increased in the MOD group(P<0.01),△ψm levels were reduced(P<0.01). Compared with the MOD group,the neurological deficit score,MPTP openness,mitochondrial swelling degree and ROS production rate were decreased in H2group(P<0.01),△ψm levels increased(P<0.01). Conclusions Simul-taneous intraperitoneal injection of pure hydrogen can reduce the generation of reactive oxygen species,protect the mitochondrial function of neuronal cells in the ischemic region after brain I/R,improvement the rat brain I/R after the neurological scoring.
